Abstract
INTRODUCTION: As women age, the increasing rate of aneuploidy lead to an augmentation in the incidence of clinical miscarriages. It was anticipated that biochemical pregnancy rates would also rise with maternal age. However, no study has previously evaluated the effect of maternal age on biochemical pregnancy rates. MATERIAL AND METHODS: A retrospective cohort study of 2177 subjects who underwent single embryo transfer (SET) as part of a fresh or thawed IVF cycle were recruited from 2008 through 2012, resulting in 952 pregnancies. Data was stratified for age and compared using analysis of variance (continuous data) and chi-squared tests (categorical data). RESULTS: = .72) (Age 21-30 y: 10.7%, Age 31-35 y:9.8%, Age 36-40y:11.5%, Age 41-42 y:13.6%). CONCLUSIONS: Biochemical pregnancy loss rate did not increase as a function of age in women 21 to 42 years of age.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
